how to add to character script functions/listen to their events?

[staarsh0werz]

i've been trying to make wanda change certain values upon changing what age_state she's in but i can't find a way to use ListenForEvent to hear the becomeage fns and i can't seem to add to her becomeold, becomenormal and becomeyoung functions. the current way i plan to do it is to simply just use ListenForEvent("healthdelta") and then depending on her current hp, push forward the changes, but wanda's script already does this and i figure it would make my experience easier and be more efficient if i could do it another way. any help is appreciated
